ORA-03264: cannot drop offline datafile of locally managed tablespace

Hi list
A datafile was acidentally created on filesystem in one node of two nodes RAC.
After that the filesystem on which the datafile was created was out of space because of automatic control file backup and sysadmin move this datafile to another device. And before this action RMAN backup stopped work.
Now we replace the datafile to the original location, but it stay offline and recover status, and we cant bring them online because the customer dont have necessary archive logs to recover this datafile. RMAN backup is now working. But now we need to create a DataGuard on a third server and want to drop this datafile.
This datafile dont have any data segment and stay in most critical tablespace of the customer application which have more datafiles. This datafile in question isnt the first datafile of the tablespace.
SQL> select file#, status from v$datafile where name='/oracle/product/db/ars/dbs/arsystem.old';
FILE# STATUS
21 RECOVER
SQL> select file#, status from v$datafile_header where name='/oracle/product/db/ars/dbs/arsystem.old';
FILE# STATUS

How can I drop this datafile?
Thanks
Cristiano

Review this metalink note, what to do:
How to 'DROP' a Datafile from a Tablespace
Doc ID:111316.1
If you cannot recover the datafile, you have to export the 'rest' of the tablespace (after statement 'alter database datafile '/oracle/product/db/ars/dbs/arsystem.old' offline drop;' was successfully issued). Afterwards drop the tablespace,recreate it and import the data).

Drop offline Datafile

Oracle Database version - 10.2.0.3
I have a tablespace with 2 datafiles. One of the datafile is offline since couple of months. Now I am trying to drop the offline datafile but its not possible to drop that datafile.
As its production environment I can not take the tablespace in offline mode.
Can anyone please suggest suitable solution to drop the datafile?

I am in the process of doing a test upgrade of Oracle E-business 11.0.3 with Oracle 8.0.6 to Oracle E-business 11.5.10.2 with Oracle 9.2.0.
I am following the upgrade manual:
Oracle Applications – Upgrading Oracle Applications
Release 11i (11.5.10.2)
Part No. B19297-01
I have already upgraded the database from 8.0.6 to 9.2.0 using the Oracle database migration utility at the appropriate point in the instructions.
After upgrading the database to 9.2.0 as stated in this manual, one of the of the next Oracle Application pre-upgrade tasks is to execute a script called addb920_nt.sql which in turn executes catalog.sql and catproc.sql. I am seeing these errors when catproc.sql is executed.
I have logged an Oracle Support SR and am awaiting a response, but wanted to know if anyone had seen similar issues.
Thanks,

ORA-02303: cannot drop or replace a type with type or table dependents

Oracle 10.2.0.3 on solaris :
I am trying to do a
CREATE OR REPLACE TYPE WickType_StringArray AS TABLE OF VARCHAR2(256);
I am getting the error :
ORA-02303: cannot drop or replace a type with type or table dependents
I then looked for the dependencies :

(Columns below with values are delimited by pipe | )
OWNER|NAME|TYPE|REFERENCED_OWNER|REFERENCED_NAME|REFERENCED_TYPE|REFERENCED_LINK_NAME|DEPENDENCY_TYPE

What is the best way for me to proceed to get my CREATE OR REPLACE statement working ?
Thanks

Well you could move to 11g but I'd suggest a less drastic measure for now. Save the data, drop the table, reload the table.
But give serious consideration to Tom Kyte's advice about object tables: Don't use them. Instead use relational tables and object views.

ORA-12983: cannot drop all columns in a table

Hi,
I am creating a table with two columns.
I have modified a column as unused using ALTER statement.
After that i have tried to drop the another column by using ALTER statement.
But it throws an error ORA-12983: cannot drop all columns in a table.
is it not possible to achieve this via ALTER statement?
thanks

is there any other way to find the name of the columns which have been marked as unused?Don't think so, and you would not be able to do much about. You won't be able to reference it, you won't be able to un-unuse it, and you would even be able to add a new column having same name.
Why are you using SET UNUSED in the first place?

Default storage for locally managed tablespaces

the documentation says you cannot have a default storage parameter for locally managed tablespaces. Does this mean that we cannot specify
INITIAL
NEXT
PCTINCREASE
MINEXTENTS
MAXEXTENTS for such tablespaces, or is there another way we can, without using default storage?
thanks

I amnot sure where you read that part that the default storage clause can't be given.Please see here,
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/tspaces.htm#sthref1149
From the doc,
Creating a Locally Managed Tablespace
If the CREATE TABLESPACE statement includes a DEFAULT storage clause, then the database considers the following:
If you specified the MINIMUM EXTENT clause, the database evaluates whether the values of MINIMUM EXTENT, INITIAL, and NEXT are equal and the value of PCTINCREASE is 0. If so, the database creates a locally managed uniform tablespace with extent size = INITIAL. If the MINIMUM EXTENT, INITIAL, and NEXT parameters are not equal, or if PCTINCREASE is not 0, the database ignores any extent storage parameters you may specify and creates a locally managed, autoallocated tablespace.
If you did not specify MINIMUM EXTENT clause, the database evaluates only whether the storage values of INITIAL and NEXT are equal and PCTINCREASE is 0. If so, the tablespace is locally managed and uniform. Otherwise, the tablespace is locally managed and autoallocated.

Locally Managed tablespaces?

Into the Design Editor, Admin tab: How can I define a tablespace as Locally Managed?

Harvinder,
Locally managed tablespaces are part of the new features of Oracle 8i. the advantages
are when they database objects need to allocate space, they need not go through the
data dictionary, they can find the free space
through bitmaps in the datafile, hence the name locally managed tablespaces.
this improves performance because recursive sql (update/insert/select of data dictionary tables) is avoided.
temporary tablespaces are prime candidates for locally managed tablespaces.
yes the whole database can be created with locally managed tablespaces..but with some restrictions. see oracle documentation for further details.

Explain local manage tablespace and dictionary manage tablespace

hi all,
kindly help me to understand local manage and dictionary manage tablespace
i have read search result and oracle corporation book still unable to understand
what i know that local is managed by bitmap(no redo) and dictionary is managed by dictionary(generates redo) plz explain this as well
and also suggest me some documentation.
thanks
Navin

Navin,
These are excerpts from Oracle documentation
Dictionary Managed Tablespace_
If you created your database with an earlier version of Oracle, then you could be using dictionary managed tablespaces. For a tablespace that uses the data dictionary to manage its extents, Oracle updates the appropriate tables in the data dictionary whenever an extent is allocated or freed for reuse. Oracle also stores rollback information about each update of the dictionary tables. Because dictionary tables and rollback segments are part of the database, the space that they occupy is subject to the same space management operations as all other data.
Lcaolly Managed Tablesapce_
A tablespace that manages its own extents maintains a bitmap in each datafile to keep track of the free or used status of blocks in that datafile. Each bit in the bitmap corresponds to a block or a group of blocks. When an extent is allocated or freed for reuse, Oracle changes the bitmap values to show the new status of the blocks. These changes do not generate rollback information because they do not update tables in the data dictionary (except for special cases such as tablespace quota information).
Locally managed tablespaces have the following advantages over dictionary managed tablespaces:
Local management of extents automatically tracks adjacent free space, eliminating the need to coalesce free extents.
Local management of extents avoids recursive space management operations. Such recursive operations can occur in dictionary managed tablespaces if consuming or releasing space in an extent results in another operation that consumes or releases space in a data dictionary table or rollback segment.
The sizes of extents that are managed locally can be determined automatically by the system. Alternatively, all extents can have the same size in a locally managed tablespace and override object storage options.

Create table with storage parameters in a locally managed tablespace

Hi,
Can we create object with storage parameters in a locally managed tablespace.
CREATE TABLE my_hash_table_6 (
name VARCHAR2(30),
value VARCHAR2(4000) )
STORAGE (
INITIAL 1M
NEXT 512K

MAXEXTENTS UNLIMITED )
users default tablespace is locallly managed.
Then this table's extent management will be managed as per the tablespace or as the storage parameters which
were specified at the time of table creation.

Why don't you try it yourself ?

Bitmap indexes to track extents in locally managed tablespaces

does any body have any idea that how oracle tracks free and used extents with bitmap indexes in locally managed tablespaces ?
please reply

There are no bitmap indexes, there is a 64k tablespace header block containing the bitmap of occupied and free extents.

Locally managed tablespaces in Apps 11.0.3

Hi,
we are on Oracle Apps 11.0.3. we recently upgraded the database to 8i ( 8.1.7.4 ). I would like to change some high activity tablespaces to locally managed tablespaces to improve performance. Are there any issues in doing this ? Can I benefit from this or will I have any issues.
thanks
Ram

We moved all the tablespaces to locally managed. Although we convereted the tablespaces to locally managed, occassionally we would see some of the ddl commands hang, cause being system still trying to update fet$ and uet$ tables. We were able to fix this by creating new locally managed tablespaces and move the contents to new locally managed tablespaces.

Downsides to Locally Managed Tablespaces?

I am creating a database from scratch and am looking at locally managed tablespaces.
Are there any downsides to locally managed tablespaces?
I understand that if the SYSTEM tablespace is locally managed, then all other tablespaces need to be locally managed. Are there any cons to this?

<quote source="AskTom.oracle.com">
Locally managed tablespaces are much faster at allocating and de-allocating
extents - many order of magnitudes faster.
locally managed tablespaces decrease contention on the data dictionary.
There is nothing bad about them, only good things.
